Calibration (CALIBRATION option)
Calibration in READING mode
The CALIBRATION option is available for viewing the calibration parameters. Scroll through the list
of parameters as they are displayed.
Calibration in PROGRAMMING mode
1. From the PROGRAMMING menu, select CALIBRATION with the scrolling keys and press Enter.
Option Description
MANUAL CAL This calibration requires two laboratory prepared calibration solutions with known
concentration.
PROCESS CAL This calibration uses the process solution, with known concentration, as the calibration
solution.
AUTOMAT. CAL This is only available if this option has been installed.
Manual calibration
1. Select MANUAL CAL and press Enter. The measurement chamber is then cleaned in
preparation for a calibration.
2. FILL BUFFER 1 is displayed. Pour the first calibration solution into the measurement chamber
and press Enter.
3. CONC 1 XX.XXEXX is displayed. Enter the calibration solution concentration and press Enter.
The solution is then measured before the measurement chamber is cleaned in preparation for the
second calibration solution.
4. FILL BUFFER 2 is displayed. Pour the second calibration solution into the measurement
chamber and press Enter.
5. CONC 2 XX.XXEXX is displayed. Enter the calibration solution concentration and press Enter.
The solution is then measured before the measurement chamber is then cleaned.
Description
From the list available, select YES for those additional options that have been
installed and NO for those not installed. For correct operation of the analyzer, any
hardware installations must have been completed before setting the option to YES.
1. AUTOMAT.CAL - Automatic calibration. Define if the automatic calibration is a
1 point or 2 point calibration. If set to 1 point, no further input is required. For
2 points, set PULSE PUMP to YES if a pulse pump has been installed or NO if a
micro piston pump has been installed and define the flow rate for the type of
pump selected. Next define the volume of the measurement cell and if the
calibration solution (STD ADDITION) is of known concentration (YES or NO).
2. CLEANING - Chemical cleaning
3. SAMPLE COND. - Sample conditioning
4. MANUAL - External sample. Set the injection time (in seconds) of the external
sample
5. HEATING - Sample heating before measurement. Set the sample temperature
required
6. DILUTION - Sample dilution before measurement
7. 2 CHANNELS - Additional sample channel. If this option is installed,
measurements are taken alternatively on each channel but calibrations are
always made on channel 1
Set the analyzer date and time parameters.
